Anemic VW TDI

If you receive a complaint from a Volkswagen owner of low power with a TDI engine, check the mass airflow sensor reading in the measuring block, group 00, field 10.

The value should reach 255 under full load.

If the reading is low, check the air filter and air box for restrictions.

If OK, suspect that the MAF is at fault.
